To understand the role of glycosylation in the circulation of cholinesterases, we compared the mean residence time of five tissue-derived and two recombinant cholinesterases (injected intravenously in mice) with their oligosaccharide profiles. Monosaccharide composition analysis revealed differences in the total carbohydrate, galactose, and sialic acid contents. The molar ratio of sialic acid t...

Herein, we report the first systematic and unbiased evaluation of the BODIPY fluorophore library against a wide panel of biologically relevant molecules, and discoveries of 2 novel fluorescent probes for BSA and dopamine.

Bovine retinol-retinol-binding protein (RBP) was isolated from serum as a free, uncomplexed protein under experimental conditions in which human, rabbit, and chicken retinol-RBP are present as tight complexes with prealbumin (thyroxine-binding protein). Purified bovine retinol-RBP formed tight complexes with purified human and chicken prealbumin in physiological ionic strength buffers as judged...

A marker's dark triplet state is of great importance in fluorescence microscopy: It serves as a means to switch off fluorescent markers and is thus the enabling element for several super-resolution methods. On the other hand, intersystem-crossing to the electronic dark triplet state strongly reduces the fluorescence yield in conventional fluorescence microscopy. The ability to determine the kin...

Mass spectrometric (MS) data of human cell secretomes are usually run through the conventional human database for identification. However, the search may result in false identifications due to contamination of the secretome with fetal bovine serum (FBS) proteins. To overcome this challenge, here we provide a composite protein database including human as well as 199 FBS protein sequences for MS ...

To each flat conformal structure (FCS) of hyperbolic type in the sense of Kulkarni-Pinkall, we associate, for all θ ∈ [(n − 1)π/2, nπ/2[ and for all r > tan(θ/n) a unique immersed hypersurface Σr,θ = (M, ir,θ) in H of constant θ-special Lagrangian curvature equal to r. We show that these hypersurfaces smoothly approximate the boundary of the canonical hyperbolic end associated to the FCS by Kul...
